Intact, non-growing Mycobacterium leprae, M. avium and M. microti oxidized a wide range of 1-14C-labelled fatty acids (C8 to C24) to 14CO2. Laurate (C12) was oxidized most rapidly, and its oxidation by M. leprae was inhibited by the antileprosy agents Dapsone, clofazamine and rifampicin. Key enzymes of beta-oxidation were detected in extracts from all three mycobacteria. All these activities (both in intact mycobacteria and the enzymes) were stimulated in M. avium grown in Dubos medium plus palmitate but activities in M. microti or M. avium grown either in Dubos medium with added liposomes or triolein, or in vivo were similar to those detected in the same strain grown in Dubos medium alone. M. avium could be grown in medium in which 95% of its fatty acyl elongase activity is acetyl-CoA dependent. In this medium growing M. avium organisms oxidized [1-14C]palmitate to 14CO2 but simultaneously elongated palmitate to C24 acids and even longer. Acetyl-CoA-dependent elongase activity is similar but clearly not identical to reversed beta-oxidation, but the exact point(s) of difference have not yet been identified.
